Answer:
The height is 5.6 units.
Step-by-step explanation:
The height can be calculated using this formula
\(h=\sqrt{a^2-\frac{b^2}{4} }\)
Let \(a\) be the base of the triangle along the horizontal.
Let \(b\) be the side of the triangle.
In an isosceles triangle has 2 sides that are equal in length.
Numerical Evaluation
In this example we are given
\(a=6\\b=3\sqrt{2}\)
Substituting our values into the equation gives us
\(h=\sqrt{6^2-\frac{\left(3\sqrt{2} \right) ^2}{4} }\)
Lets solve for \(h\).
Evaluate \(6^2\).
\(h=\sqrt{36-\frac{\left(3\sqrt{2} \right) ^2}{4} }\)
Apply the product rule to \(3\sqrt{2}\).
\(h=\sqrt{36-\frac{3^2\sqrt{2}^2 }{4} }\)
Evaluate \(3^2\).
\(h=\sqrt{36-\frac{9\sqrt{2}^2 }{4} }\)
Rewrite \(\sqrt{2}^2\) as \(2\).
\(h=\sqrt{36-\frac{9*2 }{4} }\)
Evaluate \(9*2\).
\(h=\sqrt{36-\frac{18 }{4} }\)
Factor \(2\) out of \(18\) and \(2\) out of \(4\).
\(h=\sqrt{36-\frac{2(9) }{2(2)} }\)
Cancel the common factor of \(2\).
\(h=\sqrt{36-\frac{9 }{2} }\)
To write \(36\) as a fraction with a common denominator, multiply by \(\frac{2}{2}\).
\(h=\sqrt{36*\frac{2}{2} -\frac{9 }{2} }\)
Combine the numerators over the common denominator.
\(h=\sqrt{\frac{36*2-9}{2}\)
Multiply \(36\) by \(2\) then subtract \(9\).
\(h=\sqrt{\frac{63}{2} }\)
Evaluate \(\sqrt{\frac{63}{2} }\).
\(h=5.6125\)
Round to nearest tenth.
\(h=5.6\)

How does changing the base number (inside the parentheses) change your graph?
Answers
Answer:
Step-by-step explanation:
Challenge 1
We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.
If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.
Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).
Remember that b cannot be negative.
===========================================
Challenge 2
In the general template provided, enter x = 0.
y = a(b)^x
y = a(b)^0
y = a(1) (1)
y = a
When x = 0 is plugged in, the result is y = a.
The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.

Finally, use decimal numbers to write an expression that represents the net change in Rylee’s bank account balance for her entire shopping trip. Use your answers from parts A through C to guide you.
PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).

Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).

-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).
The net change to her banking account balance is $83.22.
What is net change?The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.
Given that, She spent $36.50 plus 8% tax. (to calculate the tax amount, we have to multiply the cost by the percentage in decimal form)
36.50 x (8/100) =$2.92 (value of tax)
Adding to the original cost
36.50+2.92 = $39.42
Then, she spent $25 to refuel her car at the gas station.
39.42 +25 = $64.42
She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase
23.50 x (20/100) = 4.7 (amount of discount)
Subtracting to the purchase
23.50 -4.7= $18.8
Hence, adding to the total cost.
64.42 +18.8 = $83.22

Jared invited his friends over for lunch. He bought a pizza and ate 3/4 of it himself before calling his friends. He called Bob, Matombe, Steve, Owen, and Bill. Now, Jared must divide the 1/4 of the pizza into 5 parts for his friends to eat.
Answer:
Step-by-step explanation:
If 1/4 is divided by 5 we can think about it as 1/4 is a quarter of a whole and we need to divide that quarter in 5 equal parts.
Story Problem:
Alexa has 5 more days to finish reading the ELA book assigned by her teacher. She still has to read 1/4 of the book. What fraction of the book she should read on each of the 5 days to ensure she will be done in time?

If Alexa reads 1/20 of the book each day she will finish the book in 5 days.
Given the volume of the cuboid is atleast 150cm3 and the surface area of the cuboid is less than 320cm2. Determine all the possible values of x by solving simultaneous inequalities.
Answers
Answer:
Step-by-step explanation:
To solve this problem, we can start by finding the possible range of values for the volume of the cuboid, which is at least 150 cm^3. The volume of a cuboid is given by the formula V = lwh, where l is the length, w is the width, and h is the height. Since the volume is at least 150 cm^3, we can set up the following inequality:
V >= 150
lwh >= 150
Next, we can find the possible range of values for the surface area of the cuboid, which is less than 320 cm^2. The surface area of a cuboid is given by the formula A = 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Since the surface area is less than 320 cm^2, we can set up the following inequality:
A < 320
2lw + 2lh + 2wh < 320
Now, we can solve these simultaneous inequalities to find the possible values of x, which represent the lengths, widths, and heights of the cuboid. To do this, we can start by finding the possible values of l, w, and h that satisfy both inequalities.
One way to do this is to rewrite the inequalities in terms of a single variable, such as l, and then solve for the possible values of l that satisfy both inequalities. For example, we could substitute the expression for the volume (lwh) and the expression for the surface area (2lw + 2lh + 2wh) into the inequality for the volume (V >= 150) and the inequality for the surface area (A < 320), respectively, and then solve for the possible values of l that satisfy both inequalities.
I hope this helps! Let me know if you have any questions or need further assistance.
The surface area of a cuboid is given by the formula A = 2lw + 2lh + 2wh, where A is the surface area and l, w, and h are the dimensions of the cuboid as described above.
We can use these formulas to write two inequalities:
V = l * w * h >= 150
A = 2lw + 2lh + 2wh < 320
To solve this system of inequalities, we can begin by substituting the expression for V into the second inequality:
2lw + 2lh + 2wh < 320
l * w * h >= 150
Next, we can divide both sides of the second inequality by l * w * h to find an expression for h in terms of l and w:
h < 320 / (l * w)
h >= 150 / (l * w)
Since h must be greater than or equal to 150 / (l * w) and less than 320 / (l * w), we can find all possible values of h by finding the values of l and w that satisfy these inequalities.
To find the values of l and w that satisfy these inequalities, we can begin by substituting the expression for h into the first inequality:
2lw + 2l(150 / (l * w)) + 2w(150 / (l * w)) < 320
3lw + 300 < 320
lw < 20
Since lw must be less than 20, we can find all possible values of l and w by listing all pairs of values that satisfy this inequality. Some possible pairs of values are (1, 20), (2, 10), (4, 5), and so on.
We can then use these values of l and w to find the corresponding values of h using the expression h = 150 / (l * w). For example, if l = 1 and w = 20, then h = 150 / (1 * 20) = 7.5. If l = 2 and w = 10, then h = 150 / (2 * 10) = 15. If l = 4 and w = 5, then h = 150 / (4 * 5) = 7.5.
Therefore, all possible values of x (which represents the length, width, and height of the cuboid) are:
(1, 20, 7.5)
(2, 10, 15)
(4, 5, 7.5)
and so on…

Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A
